Allina Health’s board has approved plans to build a larger clinic in Champlin and relocate an Uptown Minneapolis facility.

Minneapolis-based Allina will pay $8 million to construct a new clinic at the site of its existing Champlin facility, 11269 Jefferson Hwy.

The size of the new clinic and other project details have yet to be determined, an Allina spokesman said.

Meanwhile, the health system is scouting for a new site for its Isles clinic in Uptown, now located at 2800 Hennepin Ave. Allina budgeted $6 million for that project, but hasn’t decided whether the facility will be larger than the old one.

Health systems across the Twin Cities are upgrading and expanding their clinic networks, partly due to health reform’s focus on reducing hospital visits through better patient care.

Hospitals still generate far more revenue for Allina than clinics do, but clinic revenue grew at a faster rate last year. Net revenue from clinics climbed 6 percent to about $645 million last year, up from nearly $609 million in 2012. That’s nearly twice the growth rate of its hospital net revenue, which rose 3.3 percent to $2.4 billion in 2013.
